Sea ice in the Weddell Sea, Antarctica

With diminishing ice one of the biggest casualties of our warming world, it’s imperative that accurate measurements continue to be made for scientific research and climate policy, as well as for practical applications such as ship routing. To ensure that ESA and NASA are getting the best out of their ice-measuring satellites and to help prepare for Europe’s new CRISTAL satellite, the two space agencies along with the British Antarctic Survey and a team of scientists teamed up recently to carry out an ambitious campaign in Antarctica.

The campaign involved taking simultaneous measurements of sea ice from ESA’s CryoSat and NASA’s ICESat-2 satellites, and from an aircraft flying directly beneath the two satellites. It is the first time that this has ever been done in the Antarctic.
